Initial momentum of first spheres = mv = 0.1�3=0.3kg m/s

initial momentum of second sphere = mv = 0.2�2 = 0.4kg m/s
After the collision
final momentum of first sphere= mv = 0.1�2.5=0.25kg m/s
final momentum of second sphere =mv =0.2�v = 0.2kg m/s
initial momentum = final momentum
0.3+0.4 = 0.25 + 0.2v
0.7 = 0.25 +0.2v
0.45 = 0.2v
v= 2.25m/s
